Is there a way to access part of a string, skip n characters, take n characters ?

[stecydube]

Is something like the following exists?

If not then I propose something like the following (I could create a feature request if needed)

Extract part of a string

substring

Returns a substring starting at index and for a given length, where length can be omitted such that the string returned is from the specified index until the end of the string.

substring (source, fromIndex, length)

take

Returns a string where only the first n characters are taken (at most)

Bonus: Could even be usable with lists of objects

take (source, count)

skip

Returns a string where the n first characters are skipped

Bonus: Could even be usable with lists of objects

skip (source, count)

Examples

• substring("This is a test", 5, 2) => "is"
• substring("This is a test", 10) => "test"
• take("This is a test", 4) => "This"
• skip("This is a test", 8) => "a test"

Could even have combinations

• take(skip("This is a test", 5), 2) => "is"
